The electorate is held by a margin of just 0.4 percent by the ALP's Darren Cheeseman, and the Opposition looks set to invest plenty of time and effort in reclaiming the seat they held for decades prior to the last election.

The Federal Opposition Leader Tony Abbott last night held a forum for around 120 undecided voters in Geelong, and he will cycle through other parts of the seat next month, including a stop in Hamilton for another community meeting.

The community members invited to last night's forum were invited to ask questions of Mr Abbott, and ABC News reporter Margaret Paul told ABC Local Radio's Steve Martin he impressed many with his straightforward answers.

"The majority of people I spoke to were happy with the result and even if last night they didn't make up their mind, they were happy that they had that opportunity and were mostly happy that Tony Abbott had explained his answers rather than speaking in soundbites."

Topics covered included support for the local car industry, employment, superannuation, immigration and gay marriage.

After the forum, the attendees were asked whether their minds had been made up by what they had heard.

Fifty people said Mr Abbott had won their vote, 17 said he hadn't and 41 said they were still undecided.

One man said it had definitely been a successful night for Mr Abbott.

"I think it was a great night for Tony Abbott, I think Tony Abbott would've made a lot of friends here tonight.

"If that was an audience of undecided people I think a lot would think that Tony Abbott was a much more friendly, approachable person than otherwise they would have thought."

Another man said he was impressed by Mr Abbott's performance.

"I think Tony is a very impressive speaker, he's across a very wide number of subjects. I am a very strong Labor supporter, I always have been, but the Labor Party at the moment are just so much on the nose that I can't in all conscience vote for them.

"But can I vote for the Liberal Party? I'm not sure."

A woman at the forum said her vote was decided by the forum and she will vote for the Liberal Party.

"The questions and the way he answered them, he didn't go around the question, he answered them direct and he answered them in-depth."
